AS2546: the ARIADNE-T Ariadne-t Network network

AS2546 is an internet Autonomous System operated by ARIADNE-T Ariadne-t Network (Greece). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS2546?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS2546 was assigned to ARIADNE-T Ariadne-t Network by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS2546 currently announces 4 IPv4 block(s), totaling about 63 thousand addresses (62,976 in all), registered in Greece. Services from ARIADNE-T Ariadne-t Network are reached through these addresses.

What it means to see AS2546 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS2546. That means the other end sits on the ARIADNE-T Ariadne-t Network network (Greece). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
